Field army units had corresponding replacement army units, which handled training new recruits, dispatching replacements, and rehabilitating the wounded. Typically, a replacement army unit would be one level smaller than its corresponding field army unit.

For example, an infantry division would typically have a replacement infantry regiment, located in its home WK. In September 1939, the WKs raised 97 infantry-type replacement regiments: 85 infantry, four motorized infantry, one Landwehr infantry, one border infantry, three mountain infantry, and three rifle. (The replacement motorized infantry regiments were for the four motorized infantry divisions, while the three replacement rifle regiments were for the rifle regiments of the six panzer divisions.) In addition, the cavalry, artillery, and engineers all had replacement formations.

Replacement Troop Commands controlled the replacement units. Each WK raised one command on mobilization; WKs with six or more replacement regiments typically raised a second command in October/November 1939. By the end of the year, the commands were designated as replacement divisions. The OB backdates these divisions to the start of the war, ignoring the commands.

Every WK had at least one training ground (Truppenubungsplatz, Troop Maneuver Area). The training grounds were the stations of the replacement divisions, schools, and other training units. Replacement army units not included in the replacement divisions are amalgamated into the training brigades, one for each major training ground.

The unit IDs on the training brigades are not actual unit designations. The training grounds were named, but trying to show this on the counters would have resulted in an alphabet soup of cryptic abbreviations. Instead, their "KStN" numbers are used as their IDs. Each type of organization in the Army had a KStN number, which was used for administrative purposes. For example, all first-wave infantry divisions had the same authorized organization and hence the same KStN number. Each training ground had its own organization and thus had a unique KStN number.

Notes

Repi Div. Replacement Divisions.

Divisional IDs in parentheses, such as "(192)," show which divisional HQs are backdated from their 1940 creation, in order to account for existing assets. The WKs of these divisions all had sufficient replacement regiments to justify having two replacement divisions, but for a variety of reasons did not form a second division until 1940.

Divisional IDs split by a slash, such as "169/148," reflect cases where the original HO was subsequently used to form seventh-wave divisions and was then replaced by a new HQ. The OB simply backdates the new HQ in place of the original.

TG Name: Training Grounds names.

KStN A, KStN numbers of the training grounds.

When WK XIII was split off from WK VII, Hohenfels Training Ground fell within the area of WK XIII but remained under the jurisdiction of WK VII.

Kleinkarpathen was under the jurisdiction of WK XVII (western Austria) but was located just across the border in Slovakia.

WK XX and XXI were created mostly from former Polish territory and had insufficient replacement units to warrant replacement divisions. Bohemia-Moravia (BM) and General Government (GG) are occupied territories rather than WKs at this time and do not have replacement divisions. Bohemia-Moravia had several major training grounds, but those in WK XX, WK XXI, and GG were nonexistent or insignificant in 1939.

In November 1939, the three western WKs transferred their replacement divisions to the east, in order to free barracks space for field army forces preparing to attack France. Thus, the 155th and 165th (WK V) relocated to Bohemia-Moravia, the 156th and 166th (WK V0 to WK XX, and the 172nd and 182nd (WK XII) to WK XXI. Despite the relocation, the original WK retained jurisdiction over the divisions.

Lehr Units

The Lehr troops were special instruction troops, part of the training establishment, and often associated with particular schools. Most arms of the German Army had a battalion- or regimental-sized Lehr unit. As the military situation demanded, these units could engage in active operations in the field.

In 1939, several Lehr formations did take the field against Poland, returning to their training duties after the campaign.

The Lehr Panzer Regiment was formed in April 1939, with a panzer battalion, a rifle (motorized infantry) battalion, and an antitank battalion. These battalions are shown independently.

An "experimental" antitank battalion was attached to the 8th Infantry Division in the Polish campaign. It was experimental in that it was using self-propelled 88mm flak guns as antitank guns (the experiment, I'd guess, was successful). It appears that this experimental unit was indeed the Lehr Antitank Battalion, and the OB thus assumes this. The other two battalions of the regiment did not take the field against Poland.

The Lehr Infantry Regiment had three infantry battalions, one of which was motorized. One nonmotorized battalion was detached to the 7th Flieger Division for possible air landing operations in Poland. Thus, one battalion of the regiment is shown independently. After the Polish campaign, the motorized battalion was reassigned to the Grossdeutschland Regiment while the detached battalion returned to its regiment from 7th Flieger. For simplicity, the OB shows the detached battalion joining Grossdeutschiand.

The Lehr Recon Battalion is a difficult unit to track. It appears that the Krampnitz Cavalry School controlled the Lehr troops for both the reconnaissance and cavalry arms, and it could raise these troops from existing assets as needed. Thus, the Kramer Cavalry Battalion that fought in the Polish campaign came from the cavalry school, probably from the same assets that officially formed the Lehr Cavalry Battalion later in 1939. The game assumes this, and it assumes the Lehr Recon Battalion is formed similarly.

The Lehr Artillery Regiment consisted of three battalions: one of horse-drawn 10.5cm howitzers, one of horse-drawn 15cm howitzers, and one of motorized 10.5cm and 15cm howitzers and guns. In late 1939, the regiment formed two additional batteries, which the OB backdates to the start of the war. The regiment did not operate against Poland.

The chemical troops had a Lehr Mortar Battalion of 10cm chemical mortars, but it did not fight in the Polish campaign.

The engineers had a Lehr Battalion of assault engineers, which did operate against the Poles.
